Lituya Bay Landslide and Tsunami Simulation Data for SPH Method Validation

The 1958 Lituya Bay landslide and tsunami event, which produced a 524-meter run-up, is modeled using a multi-phase incompressible smoothed particle hydrodynamics (SPH) method. Antonios Xenakis developed this method, which includes non-Newtonian rheology, soil saturation, and turbulence modeling. This work demonstrates the method's ability to realistically reproduce both the run-up and landslide-entry profile documented in a benchmark experiment.

Use Cases

• Validating numerical models for landslide-generated tsunamis based on the documented 1958 Lituya Bay event.
• Studying the interaction between landslide-entry profiles and water based on the described multi-phase SPH method.
• Analyzing sensitivity to initial experimental conditions as considered in the methodology.
• Benchmarking free-surface and multi-phase flow simulations against the described realistic implementation of physics.

Strengths

• Focuses on a well-documented, real-world event with a specific run-up height of 524 meters.
• Describes a novel methodology that is the first to realistically reproduce both run-up and landslide-entry profiles for this benchmark.
• The model incorporates multiple physical processes, including non-Newtonian rheology, soil saturation, and turbulence.

Limitations
